Message

At British American Tobacco GSD (Kuala Lumpur) Sdn Bhd, I manage major enterprise security incidents from detection through containment, investigation, and preventive remediation. I also work with factory directors to identify threats in OT networks and mitigate risks to production.

At Genpact, I managed security program initiatives and 24/7 team operations, and presented security dashboards to senior leadership. I also refined global SIEM use cases, reducing legacy alert fatigue by 10% on a consecutive quarterly basis.

Earlier, I conducted memory, host, and network forensics at IQVIA Pvt. Ltd. and supported detection rule development at CGI Pvt. Ltd. My work spans incident response, threat hunting, cloud security, and OT protection, backed by CCSK V2 and CTIA V2 certifications.
